Ok, so, basically, the rear cassette on my bike is giving me a lot of problems, and I'm not exactly a professional cyclist who would know where to begin so I thought I'd ask here;
The problem seems to sit with the chain going where chains shouldn't go. The other day when I was cycling along I chained gear for a hill or something, and there was a loud clunk and suddenly I could not move the pedals anymore. I got off my bike and had a look and the chain had gone beyond the casette and into the gap between the casette and the circular plastic gaurd that is up against the spokes.. It took litterally all of my strength to get it back out as it had wedged itself in there quite firmly.
I really don't know why that happened but I get the feeling something is wrong that needs fixing. I also have this odd behaviour with the rear casette, to go from gear 1 to 2, I have to twist the gear thing up to about halfway between 2 and 3, before i'll hear the chain move across, when left like this, I hear a scraping sound, and the way I stop that scraping sound is by twisting the gear thing back to just under 2. Perhaps something is misaligned?
I can only seem to use gear 1 through 4 on the front aswell but there are more gears it'll just never go into.
My bike gets knocked around alot and I guess it's abit abused, so could something have broken?
